Caspar David Friedrich, a German Romantic painter who loved showing nature as vast, quiet, and full of feeling.
A man stands on a rocky peak with his back to us, looking out over a sea of soft white fog and distant mountains.
Painted around 1818, it became a symbol of curiosity and wonder, inviting us to imagine what the traveler is thinking.
Friedrich used misty grays and blues so the fog looks endless, making one small person feel part of something huge.
Because we only see the man's back, we can pretend we are the ones standing on the mountain, looking out.
You can see it at the Kunsthalle museum in Hamburg, Germany, where it is one of the most famous paintings.
This picture appears on posters and book covers all over the world because it makes people feel brave and thoughtful.
